| 中文摘要 | Temperature and field induced magnetic phase transition in the magnetocaloric compound of LaFe11.7Si1.3 was investigated by means of Mossbauer spectroscopy and magnetization measurements. A coexistence of a magnetically split sextet and a paramagnetic doublet was observed in the temperature region of similar to185-190 K from zero-field Mossbauer spectra. A thermal hysteresis was verified between the heating and cooling processes that similar as observed in the thermomagnetic curves indicate that a first-order transition occurred in this compound. At the magnetic and paramagnetic phase coexisted region, the in-field Mossbauer measurements indicate that a span external fields from similar to1 to similar to2 T induced a magnetic phase transition as the temperature induced transformation. The in-field Mossbauer spectroscopy confirms that the field-induced magnetic phase transition is first-order phase transition as temperature-induced transition occurred in LaFe11.7Si1.3. |
