摘要：
An AlTiC-based substrate suitable for a thin-film magnetic head is provided. The Al2O3—TiC based substrate for a thin-film magnetic head including an Al2O3 phase and a TiC phase, wherein a c-axis lattice constant of the Al2O3 phase is 12.992 Å or more and 12.998 Å or less, and a lattice constant of the TiC phase is 4.297 Å or more and 4.315 Å or less.
