Strong coupling between localized atomic vibrations and spin fluctuations in a magnetic shape-memory alloy

Caption

Strong coupling between localized atomic vibrations and spin fluctuations increases the absorption and release of heat, shown from the bottom to the top, in a magnetic shape-memory alloy, improving its capacity for solid-state cooling.
