Sk. Asadov et al., THE ROLE OF STRUCTURAL TRANSFORMATIONS IN MAGNETIC-BEHAVIOR OF FLUOROSILICATES OF 3D TRANSITION-METALS, Journal of physics. Condensed matter, 9(34), 1997, pp. 7161-7171
The stability of the structural phases in the fluorosilicate hexahydra
tes of some 3d transition metals MSiF6.6H(2)O where M = Mn, Fe, Co and
Ni is studied in a wide range of temperatures and pressures. The resu
lts are generalized in the form of a P-T phase diagram of crystal stat
es. The triple points, new high-pressure phases and wide ranges of met
astable states between them have been discovered. The correspondence b
etween structural and magnetic P-T phase diagrams of the series is est
ablished.
