Researchers around the world are racing to reproduce the findings of the Quantum Energy Research Center in Seoul, which claims that a material called LK-99 has superconducting properties at room temperature and ambient atmospheric pressure.Excitement for LK-99, which is claimed to be superconducting at room temperature, is waning as more research teams are unable to reproduce the original findings. Even repeating the study from a university in the USA, the research team reported that LK-99 did not show any superconductivity.
LK-99: Replicated material does not show superconductivity
So far, researchers from three countries have discovered that as the temperature drops, LK-99 exhibits a remarkable semiconducting or insulating resistance. Meanwhile, the Condensed Matter Center (CMTC) at the University of Maryland in the USA became the first major institution to disprove the superconductivity claims in the newly synthesized LK-99 material.
The US-based research center referred to studies conducted in China, India and Taiwan to refute this claim. In one of these studies by researchers at the National Physical Laboratory in India, it was found that the sample copies of LK-99 did not show superconductivity, only diamagnetism.
On social media platform X (formerly Twitter), CMTC noted that many materials, including lead and copper, which are components of the LK-99, exhibit diamagnetism. Similarly, in the research conducted by ICQM in China, trace ferromagnetism was detected indicating attraction towards both magnet poles. We will explain what these two terms are at the end of the article.
“With great sadness, we believe the game is over now,” CMTC said in a statement. The LK99 is NOT a superconductor, even at room temperature (or at very low temperatures). It is a low quality material with very high resistance.” used the phrases.
Both these articles and researchers from the National Taiwan University (NTU) collectively reveal key issues that challenge the LK-99 claims. The researchers discovered that as the temperature drops, LK-99 exhibits a remarkable semiconducting or insulating resistance. To put it bluntly, LK-99 is far from being a superconductor, and that makes all the buzz about airborne particles pointless.
LK-99 is not a superconductor at room temperature
Conductive materials resist current flow, resulting in a large loss of energy. But a superconducting material has a transition temperature at which its internal resistance drops to zero. South Korean researchers had claimed that the LK-99 was able to achieve this at room temperature, making the material potentially useful in many everyday tasks.Now that such claims have been refuted, perhaps we can direct global attention to real advances in science.
What is Diamagnetism and Ferromagnetism?
Diamagnetism: Diamagnetism refers to the ability of materials to react weakly to magnetic fields. Such materials create a temporary magnetic moment under the influence of the magnetic field, but this moment also disappears when the magnetic field is removed. That is, diamagnetic materials do not retain the magnetic field permanently. Diamagnetism is a fundamental property generally found in all materials, but its effect is usually very weak.
Ferromagnetism: Ferromagnetism, on the other hand, refers to the ability of materials to react strongly to magnetic fields. Such materials develop a permanent magnetization when exposed to a magnetic field, and this magnetization continues even when the magnetic field is removed. Some metals such as iron and magnets are examples of ferromagnetic materials. Ferromagnetic materials attract the magnetic field and retain their magnetic properties for a long time.
In summary, diamagnetism refers to a weak and temporary magnetic response, while ferromagnetism refers to a strong and permanent magnetic response.
