| Summary: | Abstract Tungsten telluride (WTe2) and silver telluride (Ag2Te) are recently developed magnetoresistive materials, and bulk composites of these materials would be extremely advantageous in improving the magnetoresistance characteristics of the individual components and expanding their applications. In this study, previously developed synthesis methods for WTe2 and Ag2Te are applied to effectively engineer WTe2 and Ag2Te bulk composites. Introducing 10% Ag2Te in the WTe2 matrix improves the magnetoresistance and lowers the critical magnetic field and higher onset temperature relative to those of pure‐phase WTe2. The relationship between the magnetoresistance performance and Ag2Te content is further explored using simulations. The onset temperature and critical magnetic field follow the Kohler rule based on resistance calculations. The excellent composite magnetoresistance of these materials will find applications in the field of electronics. |
