| 摘 要： | This paper studies the critical behaviours and magnetic properties ofthree-dimensional bond and anisotropy dilution Blume--Capel model (BCM) in thepresence of an applied field within the effective field theory. The trajectory oftricritical point, reentrant transitions and degenerate patterns of anisotropy areobtained both for the bond and the anisotropy dilutions. The global phase diagramsdemonstrate unusually reentrant phenomena. The temperature dependences ofmagnetization curves undergo remarkable spin glass behaviour at low temperatures,and transform from ferromagnetism to paramagnetism at high temperature in appliedfields. Temperature dependence of magnetic susceptibility curve is in qualitativeagreement with experimental result.
