Query: Unprecedentedly Wide Curie-Temperature Windows as Phase-Transition
  Design Platform for Tunable Magneto-Multifunctional Materials   A series of unprecedentedly wide Curie-temperature windows (CTWs) between 40
and 450 K are realized by employing the isostructural alloying principle for
the strongly coupled magnetostructural phase transitions in a single host
system. The CTWs provide a design platform for magneto-multifunctional
multiferroic alloys that can be manipulated in a quite large temperature space
in various scales and patterns, as well as by multiple physical fields.
