Notes:
SQUID susceptometric measurements of bulk GaAs in the temperature range 5〈T〈400 K, show the longitudinal dc susceptibility χ(T) is not independent of temperature. Over this range of T the net susceptibility is diamagnetic, but with different sensitivity to temperature change. For T(approximately-less-than)50 K, χ(T) changes rapidly with T. Occasional discontinuous jumps in χ(T) are also observed. Above ∼150 K, χ(T) is less sensitive to T. Large qualitative and quantitative difference may be seen in the data obtained under different experimental protocols. We anticipate that the low-temperature magnetic behavior of other semiconductors of this type will also be anomalous. This is particularly important because these materials are extensively employed in many electronic devices.
