Abstract

<abstract abstract-type="graphical"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The last two decades have witnessed an ever increasing interest in multiferroics, i.e. materials with more than one primary order parameter simultaneously (ferromagnetism, ferroelectricity, ferroelasticity and ferrotoroidicity). In particular the formation of multiple ferroic glasses (magnetic, polar and strain glass) have become the focus of intensive research. In this special issue we have collected a series of articles from world‐class experts dealing with different aspects of ferroic glasses (see also the Preface on pp. <ext-link ext-link-type="uri" xlink:href="http://doi.wiley.com/10.1002/pssb.201470165" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">1965–1966</ext-link>). The cover illustration schematically displays the complex phase diagram of a martensitically transforming alloy which shows the appearance of a strain glass phase in the 'premartensitic or tweed region' above the martensite transformation temperature as has been observed for Ni–Ti– (Fe), Ni–Co–Mn–Ga, relaxor ferroelectrics (PLZT) and other ferroelectrics (BNT‐xBT) where the non‐ergodic behavior has been evidenced by zero‐field‐cooled (ZFC) and field‐cooled (FC) measurements (for the corresponding 'material specific effective field'). This behavior is indicated in the figure by the solid blue line (FC) and the dashed line (ZFC); <italic>T</italic><sub><italic>g</italic></sub> denotes the strain‐glass freezing temperature and <italic>M</italic><sub><italic>s</italic></sub> the martensite start temperature. For the magnetic intermetallic Heusler alloys we may in addition observe cluster‐spin glass behavior. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh1fddrzvt" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
