Query: B-site spin-state and anti-site disorder driven multiple-magnetic
  phases: Griffiths phase, re-entrant cluster glass and exchange bias in double
  perovskite Pr$_2$CoFeO$_6$   We report the comprehensive experimental results identifying the magnetic
spin ordering and the magnetization dynamics of a double perovskite Pr2CoFeO6
by employing the (dc and ac) magnetization, powder neutron diffraction (NPD)
and X-ray magnetic circular dichroism (XMCD) techniques. X-ray diffraction and
neutron diffraction studies revealed that Pr2CoFeO6 adopts a B-site disordered
orthorhombic structure with space group Pnma. Additionally, ab initio band
structure calculations performed on this system suggested an insulating
anti-ferromagnetic (Fe-Fe) ground state. Magnetometry study showed the system
to possess a spectrum of interesting magnetic phases including long range
antiferromagnetic (canted) spin ordering (TN ~269 K), Griffiths phase,
re-entrant cluster glass (RCG) (TG~ 34 K) and exchange bias. However, the NPD
study divulged the exhibition of a long range G-type (below TN ~269 K) of spin
ordering by Fe spins. Spin dynamics study by ac susceptibility technique
confirmed the system possessing long range ordering at higher
temperatureundergoes a RCG transition at ~34 K. Existence of Griffiths phase
was confirmed by non-analytic field variation of magnetization and Heisenberg
type temporal spin relaxation above long range ordering temperature TN ~269 K.
The anti-site disorder related to the B-sites (Co/Fe) is found to be the main
driving force forthe observed multiple magnetic phases. Furthermore, the
electronic structure probed by the X-ray absorption spectroscopy (XAS) study
suggested a nominal valance state of +3 for both of the B-site ions (Co/Fe)
which in turn triggered the anti-site disorder in the system. Magnetic, XRD,
NPD and XAS analysis yielded a low spin state (LS) for the Co3+ ions. The
random non-magnetic dilution of magnetic Fe3+ (HS) ions by Co3+ (LS) ions
essentially played a crucial role in manifesting the magnetic properties of the
system.
