The phrase "ac susceptibility" is correct and usable in written English.
It is typically used in scientific or technical contexts, particularly in discussions related to alternating current (AC) and its effects on materials or systems.
Example: "The ac susceptibility of the material was measured to determine its response to external magnetic fields."
Alternatives: "alternating current susceptibility" or "AC response".
SPIONPs under AC field excitation generally expressed the characteristics of AC susceptibility.
The alternating current (AC) susceptibility measurements were performed using a Lake Shore AC susceptometer (Model 7000, Westerville, OH, USA).
The effects of different factors, such as, frequency and amplitude of AC applied magnetic field and/or amplitude of DC applied magnetic field, were investigated on the AC susceptibility in Bi2223 HTS tapes.
In this study, AC losses in Bi2223 (HTS) tapes were measured by vibrating sample magnetometer at 77 K and AC susceptibility meter.

The mechanism entails examining the in-phase component of the AC susceptibility of SPIONPs.
Temperature variation of first and third order AC susceptibilities is in good agreement with Wohlfarth׳s Model for Superparamagnetism (SPM).
Measurements of magnetization and AC-susceptibility as a function of temperature were performed with a quantum design SQUID magnetometer.
In addition, the variable-temperature (2.0 12 K) ac magnetic susceptibility measurements on 2a and 2b show an intriguing frequency-dependent magnetic behavior characteristic of a spin-glass dynamics.
In this work, ac magnetic susceptibility, Mössbauer spectroscopy, X-ray diffraction (XRD) and scanning electron microscopy have been employed to study the structural and thermal evolution of a mechanochemically activated Ti Fe3O4 mixture, with molar ratio Ti Fe3O4 of 1 2.
Magnetic measurements showed that ferromagnetic interactions dominate in 1 and the AC magnetic susceptibility revealed two limit regimes in accordance with the single chain magnet and spin-glass behavior.
