• The temperature- and angle-dependent microwave response in Cr 3 Te 4 single crystal is investigated by the electronic spin resonance (ESR). • Two resonance lines are observed for both H//ab and H//c, which are suggested to result from the ferromagnetic (FM) and antiferromagnetic (AFM) fluctuations respectively, confirming the coexistence of FM and AFM coupling in this system. • The angle-dependent ESR spectra exhibit strong anisotropic microwave responses in single crystal Cr 3 Te 4 , which might benefit to the microwave-based spintronic device. [Display omitted] Chromium telluride Cr 3 Te 4 with intrinsic room-temperature ferromagnetism has substantially practical application in spintronics. In this work, the microwave response of Cr 3 Te 4 single crystal is investigated by the electronic spin resonance (ESR) with the magnetic field applied along various directions. Two resonance lines are observed for both H / / a b and H / / c , which are suggested to result from ferromagnetic (FM) and antiferromagnetic (AFM) fluctuations respectively. The angle-dependent ESR spectra show considerable anisotropy, with a strong microwave response for H / / a b and a weak microwave response for H / / c. The analysis of the ESR spectra reveals the coexistence of FM and AFM fluctuations in this system. Moreover, this anisotropic microwave response in single crystal Cr 3 Te 4 could benefit the microwave-based spintronic device. [ABSTRACT FROM AUTHOR]
