It is found that La_{2-2x}Ca_{1+2x}Mn_2O_7 (x=0.25) is a metallic ferromagnet with a magnetic\ntransition temperature T_c of 215 K. The large magnetoresistance (MR) effect with \u0394\u03c1/\u03c1_0 of \uff5e 60%\nat 1.8 T was observed in a wide temperature range below a cusp temperature in resistivity of 96 K,\nwhich is well below the magnetic T_c . This behavior is quite different from that of the well-known\ndouble-exchange ferromagnets such as La_{1-x}Ca_xMnO_3, where large MR effects are restricted to a\nnarrow temperature range around the ferromagnetic transition. The present result could be\ninterpreted by using the double-exchange theory incorporating the anisotropy resulting from the\ntwo-dimensional Mn-O-Mn networks in La_{2-2x}Ca_{1+2x}Mn_2O_7.", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/6988"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Institute of Physics"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://dx.doi.org/10.1063/1.115755", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "Copyright (1996) American Institute of Physics.
