摘　　要：The properties of color-flavor locked strange quark matter in an external strong magnetic field are investigated in a quark model with density-dependent quark masses.Parameters are determined by stability arguments.It is found that the minimum energy per baryon of the color-flavor locked(MCFL)matter decreases with increasing magnetic-field strength in a certain range,which makes MCFL matter more stable than other phases within a proper magnitude of the external magnetic field.However,if the energy of the field itself is added,the total energy per baryon will increase.The properties of color-flavor locked strange quark matter in an external strong magnetic field are investigated in a quark model with density-dependent quark masses. Parameters are determined by stability arguments. It is found that the minimum energy per baryon of the color-flavor locked （MCFL） matter decreases with increasing magnetic-field strength in a certain range, which makes MCFL matter more stable than other phases within a proper magnitude of the external magnetic field. However, if the energy of the field itself is added, the total energy per baryon will increase.
