| 英文摘要 | Ga1-xmnxas films with exceptionally high saturation magnetizations of approximate to 100 emu/cm(3) corresponding to effective mn concentrations of x(eff)approximate to 0.10 still have a curie temperature t-c smaller than 195 k contradicting mean-field predictions. the analysis of the critical exponent beta of the remnant magnetization-beta = 0.407(5)-in the framework of the models for disordered/amorphous ferromagnets suggests that this limit on t-c is intrinsic and due to the short range of the ferromagnetic interactions resulting from the small mean-free path of the holes. this result questions the perspective of room-temperature ferromagnetism in highly doped gamnas. |
