【摘要】 采用化学镀工艺制备了Co-P磁记录薄膜,研究了非晶无磁Ni-P底层对Co-P薄膜的生长及性能的影响。研究结果表明:非晶无磁Ni-P底层对Co-P薄膜的晶体结构及取向无明显影响,镀态的Co-P薄膜均为密排六方结构,(100)(、002)、(101)的择优取向无明显变化;但非晶无磁的Ni-P底层可以提高薄膜的均匀性和一致性,表面无明显缺陷;细化晶粒,平均晶粒尺寸为100~150nm;提高Co-P薄膜的磁性能,矫顽力可达4.54×104A/m。当记录信号脉冲时,与铝基体上直接施镀相比,在Ni-P底层上的Co-P磁记录薄膜输出信号幅值均匀稳定,信噪比良好。更多还原

【Abstract】 Magnetic recording Co-P thin films were prepared by electroless deposition.The influence of amorphous nonmagnetic Ni-P underlayer on Co-P thin film growth and properties was studied.The results indicated that,the amorphous nonmagnetic Ni-P underlayer didn’t have an obvious effect on the structure and texture of the Co-P thin f lms.However,it can improve the uniformity,consistency and magnetic properties of the Co-P thin films,and refine the grains.When recorded pulse signals,the Co-P magnetic recording thin films with Ni-P underlayer have a uniform and steady output and good signal to noise ratio compared with that deposited directly on aluminium substrates.更多还原
