Abstract : Single crystals of Mn(2+)-doped alpha-Sr2P2O7 have been studied by electron spin resonance at 35 Gc/sec. The space-group ambiguity has been resolved bacause the Mn(2+) ions lie on a mirror plane, and therefore the unit cell must be centric. The spin-Hamilitonian parameters have been determined. Only one EPR active site has been found rather than the two anticipated on crystallographic grounds. No evidence of a crystallographic phase transformation was found in the temperature range 100-300K. (Author)
