| 附注 | a systematic study of magnetic circular dichroism (mcd) was carried out in a wave length range 500-960 nm for (ga1-x, cr-x)as epilayers with x = 2.38% and 4.59% grown by the low temperature molecular beam epitaxy (lt-mbe) technique. hysteresis characteristics showed up indeed in the magnetic field dependence of both mcd and magnetization measured by the superconductor quantum interference device (squid). the curie temperature of the (ga1-x, cr-x)as epilayer was determined to be about 12 k by the arrott approach. the present result provides evidences that there is strong coupling of the cr spins to the gaas host band structure in (ga1-x, cr-x)as samples. that affects the critical point of the semiconductor host, and makes the magnetization behavior in a plot of m similar to b/t (magnetic field divided by temperature) substantially different from standard superparamagnetism.
