      abstract     = {The critical properties of orthorhombic Pr0.6Sr0.4MnO3
                      single crystals were investigated by a series of static
                      magnetization measurements along the three different
                      crystallographic axes as well as by specific heat
                      measurements. A careful range-of-fitting-analysis of the
                      magnetization and susceptibility data obtained from the
                      modified Arrott plots shows that Pr0.6Sr0.4MnO3 has a very
                      narrow critical regime. Nevertheless, the system belongs to
                      the three-dimensional (3D) Heisenberg universality class
                      with short-range exchange. The critical exponents obey Widom
                      scaling and are in excellent agreement with the single
                      scaling equation of state M(H,epsilon) = vertical bar
                      epsilon vertical bar(beta) f(+/-)(H/vertical bar epsilon
                      vertical bar((beta+gamma)); with f(+) for T > T-c and f(-)
                      for T < T-c. A detailed analysis of the specific heat that
                      account for all relevant contributions allows us to extract
                      and analyze the contribution related to the magnetic phase
                      transition. The specific heat indicates the presence of a
                      linear electronic term at low temperatures and a prominent
                      contribution from crystal field excitations of Pr. A
                      comparison with data from literature for PrMnO3 shows that a
                      Pr-Mn magnetic exchange is responsible for a sizable shift
                      in the lowest lying excitation.},
