If these two parts remain decoupled, they give rise to the coexistence of distinct features. Here, we show that the moment in Nd2Hf2O7 forms a static long-range ordered ground state, a flat, gapped pinch point excitation, and dispersive excitations. These results confirm recent theories which predict that the dispersive modes, which arise from the divergence-full moment, host a pinch point pattern of their own, observed experimentally as “half-moons.”}, cin = {JCNS-FRM-II / MLZ / JCNS-2 / JCNS-4}, ddc = {530}, cid = {I:(DE-Juel1)JCNS-FRM-II-20110218 / I:(DE-588b)4597118-3 / I:(DE-Juel1)JCNS-2-20110106 / I:(DE-Juel1)JCNS-4-20201012}, pnm = {6G4 - Jülich Centre for Neutron Research (JCNS) (FZJ) (POF4-6G4) / 632 - Materials – Quantum, Complex and Functional Materials (POF4-632)}, pid = {G:(DE-HGF)POF4-6G4 / G:(DE-HGF)POF4-632}, experiment = {EXP:(DE-MLZ)DNS-20140101}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000858959100003}, doi = {10.1103/PhysRevB.106.L100401}, url = {https://juser.fz-juelich.de/record/909940}, }
