## Abstract

We consistently observe a unique pattern in remanence in a number of canted-antiferromagnets (AFM) and piezomagnets. A part of the remanence is $\\textit{quasi-static}$ in nature and vanishes above a critical magnetic field. Present work is devoted to exploring this $\\textit{quasi-static}$ remanence ($\\mu$) in a series of isostructural canted-AFMs and piezomagnets that possess progressively increasing N\\'eel temperature ($T{\_N}$). Comprehensive investigation of remanence as a function of $\\textit{magnetic-field}$ and $\\textit{time}$ in CoCO$\_{3}$, NiCO$\_{3}$ and MnCO$\_{3}$ reveals that the magnitude of $\\mu$ increases with decreasing $T{\_N}$, but the stability with time is higher in the samples with higher $T{\_N}$. Further to this, all three carbonates exhibit a universal scaling in $\\mu$, which relates to the concurrent phenomenon of piezomagnetism. Overall, these data not only establish that the observation of $\\textit{quasi-static}$ remanence with $\\textit{counter-intuitive}$ magnetic-field dependence can serve as a foot-print for spin-canted systems, but also confirms that simple remanence measurements, using SQUID magnetometry, can provide insights about the extent of spin canting - a non trivial parameter to determine. In addition, these data suggest that the functional form of $\\mu$ with $\\textit{magnetic-field}$ and $\\textit{time}$ may hold key to isolate Dzyaloshinskii Moriya Interaction driven spin-canted systems from Single Ion Anisotropy driven ones. We also demonstrate the existence of $\\mu$ by tracking specific peaks in neutron diffraction data, acquired in remnant state in CoCO$\_{3}$.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
