The value of phi can be chosen by design in the interval 0 < phi < pi. The junctions used in our experiments are fabricated as 0-pi Josephson junctions of moderate normalized length with asymmetric 0 and pi regions. We show that (a) these phi Josephson junctions have two critical currents, corresponding to the escape of the phase c from -phi and +phi states, (b) the phase psi can be set to a particular state by tuning an external magnetic field, or (c) by using a proper bias current sweep sequence. The experimental observations are in agreement with previous theoretical predictions. 000022767 536__ $$0G:(DE-Juel1)FUEK412$$2G:(DE-HGF)$$aGrundlagen für zukünftige Informationstechnologien$$cP42$$x0 000022767 588__ $$aDataset connected to Web of Science 000022767 650_7 $$2WoSType$$aJ 000022767 7001_ $$0P:(DE-HGF)0$$aLipman, A.$$b1 000022767 7001_ $$0P:(DE-Juel1)VDB59925$$aWeides, M.$$b2$$uFZJ 000022767 7001_ $$0P:(DE-HGF)0$$aMints, R.G.$$b3 000022767 7001_ $$0P:(DE-Juel1)VDB3107$$aKohlstedt, H.$$b4$$uFZJ 000022767 7001_ $$0P:(DE-HGF)0$$aKoelle, D.$$b5 000022767 7001_ $$0P:(DE-HGF)0$$aKleiner, R.$$b6 000022767 7001_ $$0P:(DE-HGF)0$$aGoldobin, E.$$b7 000022767 773__ $$0PERI:(DE-600)1472655-5$$a10.1103/PhysRevLett.109.107002$$gVol. 109, p. 107002$$p107002$$q109<107002$$tPhysical review letters$$v109$$x0031-9007$$y2012 000022767 8567_ $$uhttp://dx.doi.org/10.1103/PhysRevLett.109.107002 000022767 8564_ $$uhttps://juser.fz-juelich.de/record/22767/files/FZJ-22767.pdf$$yOpenAccess$$zPublished final document. 000022767 8564_ $$uhttps://juser.fz-juelich.de/record/22767/files/FZJ-22767.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000022767 8564_ $$uhttps://juser.fz-juelich.de/record/22767/files/FZJ-22767.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000022767 8564_ $$uhttps://juser.fz-juelich.de/record/22767/files/FZJ-22767.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000022767 909CO $$ooai:juser.fz-juelich.de:22767$$pdnbdelivery$$pVDB$$pdriver$$popen_access$$popenaire 000022767 915__ $$0LIC:(DE-HGF)APS-112012$$2HGFVOC$$aAmerican Physical Society Transfer of Copyright Agreement 000022767 915__ $$0StatID:(DE-HGF)0010$$2StatID$$aJCR/ISI refereed 000022767 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR 000022767 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000022767 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000022767 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000022767 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000022767 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000022767 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000022767 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000022767 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000022767 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000022767 915__ $$0StatID:(DE-HGF)1020$$2StatID$$aDBCoverage$$bCurrent Contents - Social and Behavioral Sciences 000022767 9141_ $$y2012 000022767 9131_ $$0G:(DE-Juel1)FUEK412$$1G:(DE-HGF)POF2-420$$2G:(DE-HGF)POF2-400$$aDE-HGF$$bSchlüsseltechnologien$$kP42$$lGrundlagen für zukünftige Informationstechnologien (FIT)$$vGrundlagen für zukünftige Informationstechnologien$$x0 000022767 9132_ $$0G:(DE-HGF)POF3-529H$$1G:(DE-HGF)POF3-520$$2G:(DE-HGF)POF3-500$$aDE-HGF$$bKey Technologies$$lFuture Information Technology - Fundamentals, Novel Concepts and Energy Efficiency (FIT)$$vAddenda$$x0 000022767 9201_ $$0I:(DE-Juel1)PGI-7-20110106$$gPGI$$kPGI-7$$lElektronische Materialien$$x0 000022767 9201_ $$0I:(DE-82)080009_20140620$$gJARA$$kJARA-FIT$$lJülich-Aachen Research Alliance - Fundamentals of Future Information Technology$$x1 000022767 970__ $$aVDB:(DE-Juel1)139521 000022767 981__ $$aI:(DE-Juel1)VDB881 000022767 9801_ $$aFullTexts 000022767 980__ $$aVDB 000022767 980__ $$aConvertedRecord 000022767 980__ $$ajournal 000022767 980__ $$aI:(DE-Juel1)PGI-7-20110106 000022767 980__ $$aI:(DE-82)080009_20140620 000022767 980__ $$aUNRESTRICTED 000022767 980__ $$aFullTexts
