The inverse magnetocaloric effect associated with the martensitic transition in Ni45.4Mn41.5In13.1 Heusler alloy is reported. A large positive magnetic entropy change of 8J∕kgK under a low field 10kOe found near temperature. This originates from first-order low-temperature weak-magnetic phase to high-temperature ferromagnetic austenitic phase. low-field indicates great potential Ni–Mn–In alloys as working materials for refrigeration wide temperature range.

We present a facile approach to produce submicrometer sized Janus PAN/PS polymer colloids by seeded emulsion polymerization.
