Two-color time-resolved magneto-optical Kerr spectroscopy is used to manipulate and detect the dynamics of carrier-induced ferromagnetism in III-V ferromagnetic semiconductors. Our data demonstrates that magnetic properties, e.g., the coercivity, can be tuned reversibly and nonthermally on subpicosecond time scale.
A polysaccharide mucilage derived from the seeds of fenugreek, Trigonella foenum-graceum L (family Fabaceae) was investigated for use in matrix formulations containing propranolol hydrochloride. Methocel hypomellose K4M was used as a standard controlled release polymer for comparison purposes. In this study the effect of lactose on the release behaviour of(More)
