Nickel hyperaccumulators have a strong potential to be used as bioindicators in mineral explorations. Previous studies show that analysis of magnetic susceptibility has a potential to accelerate the screening of Ni hyperaccumulators. In this study, we investigated the use magnetic characterizations for screening directly Ni hyperaccumulators and non-Ni hyperaccumulators from ultramafic regions. For comparison, the characterization of Ni hyperaccumulators was also performed on Alyssum murale and Alyssum corsicum, which were cultivated on lateritic soils. The metals concentrations in the tissues were determined via inductively coupled plasma optical emission spectroscopy analysis, atomic absorption spectroscopy analysis, and X-ray fluorescence analysis. The magnetic characterizations were conducted by magnetic susceptibility measurement, acquisition of hysteresis curves, and analysis of the thermomagnetic properties. The results showed that the concentration of Ni in A. murale and A. corsicum were correlated to the magnetic susceptibility values. Concurrently, all samples had negative magnetic susceptibility values were non-Ni hyperaccumulators. Two new species of Ni hyperaccumulators were found in Halmahera and Sulawesi and have high potential for use in phytoremediation, phytomining or mineral exploration.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Atomic absorption spectroscopy,Inductively coupled plasma-optical emission spectroscopy,Magnetic characterization,Magnetic susceptibility measurements,Metals concentrations,Ni-hyperaccumulators,Thermomagnetic properties,X ray fluorescence analysis[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Magnetic characterizations,Ni hyperaccumulators[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][{‘$’: ‘This research was funded by the research grants received by S.
