【摘要】 采用化学镀法制备了Co-P磁记录薄膜。当薄膜厚度为0.3μm时,矫顽力可达4.54×104A/m,剩余磁化强度为0.068T。X射线衍射分析表明,当Co-P薄膜较薄时,薄膜结构中无明显择优取向,晶粒较小,此时矫顽力较高;当厚度增加至3-4μm以上时,结构中择优取向明显,晶粒较大,此时薄膜的矫顽力较低。将其应用于磁旋转编码器的磁鼓记录介质,制成直径Φ40mm的磁鼓,当原始充磁磁极对数为512时,脉冲计数完整,输出信号强,波形稳定。更多还原

【Abstract】 Magnetic Co-P thin films were prepared by electroless deposition.When the thickness of the film was 0.3μm,the coercivity got 4.54×104A/m,and the remanent magnetization(Mr) got 0.14T.The XRD patterns indicated that,when the Co-P films were thinner,the prevailing orientation of crystalline grains was not obvious,with smaller grains size and higher coercivity;when the film thickness was beyond 3～4μm,the prevailing orientation was obvious,with larger grains size and lower coercivity.The Co-P film was applied to the magnetic drum,whose diameter was 40mm,and then was recorded 512 magnetic poles.The output signals were perfect,and the output waveforms were steady.The pulses account was integral.更多还原
