摘要:

Reentrant spinelsLi0.5Fe2.5−xGaxO4withx=0.9and 1.2 display peaks on the temperature dependences of heat capacityCatT1=13.4&hthinsp;K&hthinsp;(x=0.9)and14.2&hthinsp;K&hthinsp;(x=1.2)respectively, which are typical of a first-order phase transition. This transition is identified with the transformation of the collinear ferrimagnetic structure into a noncollinear structure preceding on the temperature scale the state of ferrimagnetic spin glass existing in the temperature range0&hthinsp;K⩽T⩽Tf,where transition temperaturesTfare9&hthinsp;K&hthinsp;(x=0.9)and12&hthinsp;K&hthinsp;(x=1.2). ©1998 American Institute of Physics.
