Giant magnetocaloric materials such as Gd5(Si2Ge2) and La(Fe,Si)13-based compounds have demonstrated adiabatic temperature changes of several kelvin per tesla of applied field near their magnetic transition temperature — among the largest magnetocaloric effects characterized, of interest for solid-state magnetic refrigeration as a potentially more efficient and refrigerant-free alternative to conventional vapor-compression cooling.

Description

Formal question

Scope & constraints

Current published specification applies.

Scope audit

Does your result fit this record?

Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.

This record has no editable parameters. Read the formal question and assumptions before challenging it.

Scope matches the published specificationNo parameters changed

What we know

Current frontiers derived from accepted Claims.

Best demonstrated value6.3

An observed or demonstrated result; no opposing bound is implied.

The frontier is not sacred

Think this record is wrong? Good.

Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.

Push the floor upPropose ≥ when you have shown that at least this value is achievable.

Pull the ceiling downPropose ≤ when you have shown that anything above this value is impossible.

No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.

How this frontier is derived

Only accepted Claims matching the current specification contribute to the displayed bounds. Strict inequalities remain open; contradictory Claims require editorial review.
