Jiles-Atherton(J-A)　model　is　widely　employed　in　the　area　of　magnetic　modeling,　however,　the　minor　hysteresis　loop　given　by　J-A　model　is　not　accurate　and　J-A　model　can　not　study　the　effects　of　temperature　on　hysteresis　loop.　In　order　to　build　an　accurate　temperature-dependent　hysteresis　loop　model,　the　methods　of　error　modification　and　temperature　simulation　on　J-A　model　are　proposed.　The　accuracy　of　minor　hysteresis　loop　is　improved　by　modifying　model　parameters　and　temperature　is　introduced　into　J-A　model　by　adding　curie　temperature,　critical　exponent　and　other　parameters.　Modeling　process　of　Fe-Si　magnetic　sheet　is　introduced　and　results　show　good　agreement　between　theory　and　experiment　and　prove　that　the　new　model　is　useful.
