英文摘要Highly ordered La0.5Ca0.5MnO3 nanowires bundles are synthesized using mesoporous SBA-15 silica as the hard template. The magnetic properties and critical behaviors of the ferromagnetic-paramagnetic (FM-PM) phase transition of the La0.5Ca0.5MnO3 nanowires bundles are investigated through isothermal magnetization methods. The calculated results show that the FM-PM transition is second order and the magnetic interaction has some deviations from the mean-field model. Though the obtained critical parameters of beta = 0.596 +/- 0.009, gamma = 1.131 +/- 0.008 and delta = 2.99 +/- 0.05 follow the Widom scaling relation delta = 1 + gamma/beta and the single scaling equation M(H,|epsilon|) = epsilon(beta)f +/- (H/|epsilon|(beta+gamma)), the critical exponents do not obey the magnetization entropy scaling theory, indicating that the nanometer-size effect play a significant role on the magnetic phase transition and magnetic entropy for La0.5Ca0.5MnO3 nanowires bundles.
