Transport properties of Li1+y(Cd1−xMnx)P: (a) ρ(T) of Li1+yCdP with y = 0, 0.05 and 0.1. (b) ρ(T) of Li1.1(Cd1−xMnx)P with x = 0, 0.025, 0.05, 0.075 and 0.1. (c) Magnetoresistance of Li1.1(Cd0.9Mn0.1)P at different temperatures. (d) Correlation between TC and the hole concentration for several “111”, “122” new types of diluted ferromagnetic semiconductors and typical III-V diluted ferromagnetic semiconductors.
